I believe that of the two possible routes here one is easy and one
hard - it would be easy to take the 3D image volumes of the masks,
transform them into a standard space (if they're not already) and
average-then-re-threshold using fslmaths. The hard way is to work with
the mesh representations instead, for which I think you would probably
need to get inside the source code to do this kind of thing - Brian/MJ
can correct me if I'm wrong.
Cheers, Steve.
